ter. In recovery the animal without its cerebrum i is dependent upon 
its sense organs to generate impulses which may eventually affect its 
cerebellum, while the normal animal may have its cerebellum influ- 
enced not only through its sense organs, but also from its centers 
for spontaneous movements in the cerebrum. Thus animals with a 
cerebrum usually recover sooner than those deprived of this organ. 
The motionless condition in animals has then only a superficial 
resemblance to certain phases of hypnotism as seen in the human 
subject, and probably is an essentially different phenomenon. _

Generic Names P Dr. Carlos Berg has done a useful 
work in a critical study of recently proposed generic names with a 
view to the elimination of those preoccupied. In Communicaciones del 
Museo Nacional de Buenos Aires, 1898, pp. 41, 43 (December 17), he 
proposes to substitute the following names of animals for others pre- 
occupied. Hoferellus for Hoferia; Iheringiana for Iheringiella ; 
Halochnaura for Asterope ; Gestroana for Gestroa ; Corynophora 
for Halterophora; Meyrickella for Prionophora ; Walsinghamiella 
for Gilbertia (Lepidoptera); Watsoniella for Watsonia ; Schochidia 
for Lophostoma ; Braunsianus for Anelpistus; Gilbertidia for Gil- 
bertina; Matzocephalus for Ccelocephalus. The last two are genera 
of American fishes. DSF 
Deep-Sea Fishes of Iceland. — Dr. Christian Lütken has just 
published, in English, a most valuable account of the fishes dredged 
by the “Ingolf” in 1895 and 1896 off Iceland and the Faroë. 
Forty-four species are recorded, three of them new, Raja ingolfiana, 
Cyclothone megalops, and Macrurus ingolfi. Important notes are given 
on the structure of different species. The lithographic plates of 
Cordts (some of them colored) which illustrate this paper are most 
excellent. S23: 
Spolia Atlantica. — Dr. Christian Lütken, of the University of 
Copenhagen, has continued his most valuable discussion of the early 
stages of development of fishes, as shown by the rich “ spoils of the 
Atlantic,” young fishes taken in the open sea. The third paper of
